[Early to mid-term results of endovascular repair of aortic dissection: report of 165 cases].
OBJECTIVE
To evaluate the early and midterm outcomes of endovascular repair of aortic dissection (AD).


METHODS
Between January 2001 and December 2006, 165 patients (145 male and 20 female) with AD were treated with endovascular repairing. The mean age of the patients was 52.8 years (range, 30-82 years). Among them, 36 patients had Stanford type A dissection, 121 had type B dissection and 8 had aortic ulcer. Among the dissection patients, 47 were acute AD (the interval between onset and surgery was < or = 7 days), 69 were subacute AD (the interval between onset and surgery was 8-30 days) and 41 were chronic AD (the interval between onset and surgery was > 30 days).


RESULTS
The stents were placed technically successfully in 164 patients (99.4%). The rate of endoleak within 30 days after placement of stents was 7.3% (12/165) and neurologic complication rate was 2.5% (4/165). The mortality rate within 30 days was 6.1% (10/165), and the mortality of acute, subacute and chronic AD was 12.8%, 1.4% and 7.3%, respectively. One hundred and forty-five cases were followed up for 6 to 75 months (median, 28.2 months). Complete thrombosis in false lumen was achieved in 62 patients (42.8%), while partial thrombosis was achieved in 83 patients (57.2%). Nine patients died during fellow-up.


CONCLUSIONS
It's indicated that endovascular repair of AD is a microinvasive, safe and effective methods for aortic dissection. However, the long-term efficacy needs to be evaluated further.
